4.4 Bleed the Lubricating Oil System
Release the air in the pipes to the lubricating quills after you have released the air in:
D The filter
D The measurement tube
D The lubricating pumps.
Do the steps that follow:
1) Loosen all union nuts on the pipes approximately two turns (see 2138−1, Fig 2).
2) In the operator interface, select the related cylinder number in the menu
MANUAL LUBRICATION ON CYL. As an alternative, set the switch to MANUAL
EMERGENCY for the related 4/2-way solenoid valve (3, Fig 5).
3) Keep the union nuts open until oil that flows has no air.
4) Tighten the union nuts.
After all the oil pipes of a cylinder are bled, you can visually examine the cylinder oil
supply as follows:
5) Make sure that the piston is in the TDC position. Look through the scavenge air
ports in the cylinder liner, while the lubricating system operates.
6) To manually release a single lube pulse, push in the assembly pin (11).
7) To do a check of the servo oil pipes, loosen the screw plug (8) a maximum two
turns. If servo oil comes out, the servo oil pipes are damaged.
